Dominic Smith did not get the call-up to the majors when Lucas Duda hit the disabled list, a move some speculated would happen to breathe life into the Mets’ offense.

But if the prospect, whom Baseball America ranked 65th in baseball this week, is discouraged, he hides it well. The Triple-A Las Vegas first baseman feels healthy and is feasting on Pacific Coast League pitching after an offseason in which he said he lost 24 pounds.

“It’s been easier to become comfortable,” said Smith, a 2013 first-round pick from California. “I’ve lost weight and am in shape. I think I’ve improved in that, and that’s helped even just running the bases, it helps with everything. I’m more agile.”

Entering this weekend, Smith was batting .328 with three home runs and eight doubles, a season after the left-hander hit .302 with 14 homers in Double-A Binghamton. He didn’t get the major league nod, but he said he is absorbing the tutelage from the Las Vegas roster.

“We have a bunch of guys that have played in the big leagues,” he said, specifically mentioning former Rays outfielder Desmond Jennings and Gavin Cecchini. “I try to study and watch what they do, they know what they’re doing.”

Rosario, a shortstop, played third base on April 21, but had not returned to the hot corner with the wave of injuries hitting the Mets. The return of Asdrubal Cabrera marked the return of the Rosario experiment, as the Mets no longer toyed with inserting him as their major league shortstop.

“When he signed he was a third baseman and they moved him to short,” Lopez said. “I’m not concerned. He has the tools to play there.”
